Description
1. FILED OF INVENTION
[0001] The present invention relates to a composition containing
fish oil and juice and the preparation thereof.
2. DESCRIPTION OF PRIOR ART
[0002] Fish oil is the richest dietary source of long-chain omega-3
polyunsaturated fatty acids (PUFA). Stabilisation of omega-3 PUFA
against oxidation is an important task in food processing.
[0003] Fatty acids are the building blocks of dietary fats. The
human body stores such dietary fats substantially in the form of
triglycerides. Triglycerides containing omega-3 fatty acids are
mainly found in fish.
[0004] The omega-3 fatty acids are essential to life at any stage,
even before birth. They are essential building blocks of the
membrane of every cell in the body and their presence are a
necessity for maintaining an adequate cell membrane. They do also
contribute in the regulation of most biological functions,
including those of the cardiovascular, reproductive, immune and
nervous systems.
[0005] The nutritional value of omega-3 for humans is well known
and recognized by scientists and medical skilled persons all over
the world. Several studies have been conducted within the field and
significant benefits have been revealed on omega-3 in relation to
the immune system, on supporting brain development and nervous
system. Other studies support benefits of omega-3 intake when
suffering from asthma or eczema. There is at present focus on the
role of Omega 3 for children suffering from ADHD or other
concentration problems.
[0006] The typical diet today gives a lack of omega-3. The Health
authorities in Norway, Mattilsynet, are now actively advising the
public to eat fish for dinner 4 times a week.
[0007] Working with marine oil preparations shows that it is
extremely difficult to prevent the oxidation of fatty acids. Event
thought the processing and storage are conducted in an inert
atmosphere, and the product are filled on air tight dose units, it
has been difficult to prevent the oxidation completely and to offer
a product where the fishy taste is eliminated or fully masked and
where the unpleasant aftertaste is no longer present.
[0008] Science has long held that damage by oxygen free radicals is
behind many of the maladies that come with aging, including
cardiovascular disease and cancer. There's firm evidence that a
high intake of fruits and vegetables reduces risk of cancer and
that a low intake raises risk. And recent evidence suggests that
diminished brain function associated with aging and disorders such
as Alzheimer's and Parkinson's diseases may be due to increased
vulnerability to free radicals, says Joseph, a neuroscientist.
[0009] Such evidence has spurred skyrocketing sales of antioxidant
vitamin supplements in recent years.
[0010] But several large trials testing individual antioxidant
vitamins have had mixed results. It may be that combinations of
nutrients found in foods have greater protective effects than each
nutrient taken alone. Fruits and berries contain hundreds of
pigments, as well as non-pigment compounds that may play a role in
preventing oxidative damage. The carotenoid pigments lutein and
lycopenepossess exceptionally high antioxidant capacity, apricot,
peaches and plums have high content of these. For example, fruits
and vegetables contain more than 4,000 flavonoids. These constitute
a major class of dietary antioxidants and appear to be responsible
for a large part of the protective effect of fruits and
vegetables.
[0011] Since long fish oil have been available on bottles wherein
the recommended daily dose is about one spoon. To provide a product
with better compliance the fish oil has been encapsulated in
different capsules, wherein the recommended daily dose is about 4-6
capsules. Encapsulated products often disguise a heavily oxidized
fish oils, and the health value of these oils are questioned by
scientist worldwide. Omega-3 enriched capsules are also
available.
[0012] Prior art the Norwegian Patent Application No 2004 4542
provides a creamy oil-in-water emulsion and Norwegian Patent
Application No E41192 provides a drink both containing fish oil,
wherein the oxidation of fatty acids is reduced to an acceptable
level.
[0013] Within the field of functional food, products containing
fish oil are available, such as bread and milk preparations etc.
Dairy Crest (UK), Dawn Dairies, (Ireland) and Muller Dairies, (UK),
lunch of fresh milk or yoghurt drinks added fish oil. The Omega 3
content of these are as follows such that about 1 litre is required
to cover the daily dosage requirements of omega-3
[0014] In the fresh milk products above the omega-3 source is a pre
made emulsion from DSM: ROPUFA 30. This high concentrated emulsion
is added to the milk just before the cartons are closed. In Muller
Vitality, which was launched November 2005, an omega-3 powder is
used. This means the omega-3 fish oil is packed and dried into a
powder form, and scientists are discussing whether it is possible
for the body to absorb these omega-3 fatty acids.
[0015] Products comprising fish oil wherein the oxidation of fish
oil has been prevented or minimized by use of antioxidants
naturally present in juice, are hitherto not been available.
[0016] Thus, there is a need for a stable and tasty composition
combining the benefits of fish-oil and naturally occurring
antioxidants in the form of juice. The present invention provides
such a composition. The composition may be provided as a drink
which may be a drink of choice both due to the health promoting
effects and when thirsty. The combination may also be provided as
creamy or pasty composition, much like yoghurt.
[0017] Further, there is a need for a combination of fish oil and
fruit juice made into ready-to-use preparations, wherein the
process of production involve a minimum of process steps and
wherein the fish oil is added directly to the composition, not as a
premade emulsion, powder or other intermediates, revealing a gentle
process harmless to the fish oil. There is a need for a
ready-to-use preparation which provides the consumers with the
daily requirement of omega-3 in small units.
3. PRESENT INVENTION
[0018] Thus the object of the present invention is to provide a new
composition combining [0019] a) fatty acids, especially omega-3
fatty acids essential for life in an aliquot sufficient to cover
the daily requirement, and [0020] b) juice containing naturally
present antioxidants
[0021] Another object of the present invention is to provide a new
palatable composition comprising fish oil, omega-3 fatty acids and
juice in a preparation without any fishy taste or after taste. The
term palatable is herein defined as a composition with a pleasant
flavor, taste and aftertaste. The content of fish oil in said
composition is from 0.5-15% by weight.
[0022] A further object of the present invention is to provide a
composition containing fish oil, wherein the quality of the refined
fish oil as a raw material is excellent.
[0023] A further object of the present invention is to provide a
method of production wherein the fish oil is handled under gentle
conditions through a minimum of process steps.
[0024] A further object of the present invention is to provide a
stable composition wherein the oxidizing processes of the fatty
acids have been lowered to a minimum. The antioxidants of the juice
play an important role in preventing oxidation and promoting
stability.
[0025] A further object of the present invention is to provide a
composition in daily dose units containing the recommended daily
dose of omega-3 fatty acid. The composition may be provided as a
drink in airtight bottles and will contribute to the maintenance of
the water balance and be a drink of choice to thirsty people. The
composition may also be provided as yoghurt like composition in
sealed containers.
[0026] These and further objects are achieved by the present
invention.
4. DETAILED DESCRIPTION OF THE INVENTION

revealing a stable, tasty and user-friendly product. Thus, the
present invention provides a new tasty composition containing fish
oil and juice.
[0028] One preferred embodiment of the present invention provides a
composition wherein the content of the fish oil is about 0.5%-15%
by weight, more preferably in the range of 2%-7% most preferably
about 2%-5%. The fish oil may be selected from any fish oil
preparation of appropriate quality. To be of appropriate quality
the level of oxidation given as the totox-value (2 times the
peroxide value (PV) added with the anisidine value (AV)) should be
below 20. Further the content of omega-3 fatty acids should be at
least 16%, preferably about 25-30%. Specifically preferred fish oil
is Denomega 100 or Denomega Trout oil. Said oils are clear oils
with a very mild fishy odour and taste.
[0029] By a content of 5% the daily requirement of fish oil are
reach by consuming about 50-100 ml of the composition according to
the invention. The recommended daily dose of omega-3 for adults are
650 mg given by ISSFAL--International Society for the Study of
Fatty Acids. The recommendation for children is about half the
dosage of an adult, i.e. 350 mg. There are strong signals from the
EU commission that there will be new guidelines on this
recommendation. From 2006/2007 the daily dosage requirements will
probably be as high as 2 gram. By a content of 5% the daily
requirement of fish oil are reach by consuming about 50-100 ml of
the composition according to the invention.
[0030] Another preferred embodiment of the present invention
provides a composition wherein the content of juice is about 30-80%

yoghurt.
[0036] Another preferred embodiment of the present invention
provides a composition wherein the composition is filled in daily
dose units, preferably airtight bottles or small sealed containers,
but any suitable container may be applicable. Containers containing
different amounts of fatty acids adjusted to the recommended daily
dose of adults, children and infant are possible. In the case the
composition according to the invention is provided as a drink, a
suitable volume is 50-200 ml. In the case the composition of the
present invention is provided as yoghurt, a suitable volume is
25-100 ml. However, any dose unit covering the recommended daily
dose can be applied.
[0037] Further, the present invention relates to a process for the
preparation the composition according to the invention comprising;
[0038] a) water soluble additives are solubilized in water and
combined with a suitable juice [0039] b) emulsifier and oil soluble
additives are mixed with fish oil of adequate quality under

easy to swallow. No smell or taste of fish oil could be experienced
by a panel of voluntaries testing the composition. No fishy
aftertaste was experienced.
5.2 Process of Production
[0061] The composition according to the invention was prepared by
the following steps; [0062] a) water soluble additives are
solubilized in water and combined with a suitable juice [0063] b)
emulsifier and oil soluble additives are mixed with fish oil of
adequate quality under continuous but gentle stirring [0064] c) the
oil phase of b) is added slowly under continuous but gentle
stirring to the water phase of a) obtaining a homogenous
oil-in-water emulsion [0065] d) the composition is filled on
suitable air tight sealed containers under inert atmosphere.
[0066] The sequence of the steps can be varied as long as a
composition of appropriate quality is achieved.
[0067] The content of fish oil is preferably between 0.5 and 15%,
most preferably between 2-5%. The juice may be any suitable juice
as outlined above.
[0068] The containers may preferably be small bottles or containers
ready to be used. Containers containing different amounts of fatty
acids and juice adjusted to the recommended daily dose of adults,
children and infant are preferred. The processing and packaging are
conducted under an inert atmosphere. The product is stored at a
temperature of 0-10.degree. C.
5.3 Performance/Stability
[0069] As indicated above, all compositions performed excellent
immediately after completing the production.
[0070] The compositions according to the invention were tested with
respect to stability.
5.3.1 Long Term Stability
[0071] Drinks and yoghurt compositions and stored illuminated at
6.degree. C., resembling the storage conditions in the stores.
[0072] The compositions were tested with respect to visual
inspection and smell, as well to oxidative status. To evaluate the
oxidative status the emulsion must be decomposed to recover the
fish. The composition were centrifuged for 1 h at 15 000 rpm.
Surprisingly the emulsion did not decompose and thus it was
impossible to recover the fish oil for oxidative status. As such
this was an eminent proof of the improved stability achieved by the
composition according to the invention.
5.3.2 14 Days Stability
[0073] Drinks comprising rosehip juice and 3% fish oil filled on
air tight containers were stored at 25-28.degree. C. for 14 days.
The screw-cap of the airtight bottle was removed and the room was
illuminated.
[0074] After 14 days no changes were observed with respect to the
appearance, smell or taste. These findings were surprisingly good
and unexpected, as compositions containing fish oil are known to be
highly unstable. Thus, a new and inventive fish oil product having
surprisingly high stability both with respect to the stability of
the emulsion and the stability of the fish oil are provided.
[0075] Without being bound to a specific theory, this is believed
to be the result of the excellent performance of the juice, the
excellent quality of the fish oil as a raw material and the gentle
process in which the fish oil is emulsified and prepared into
ready-to-use products.
